# Formatting number values

Values of Number custom fields or number constants may be formatted in email templates in various ways. The key to number formatting is the `$!number` variable which is an instance of the NumberTool Jira API class. NumberTool provides buit-in styling for formatting numbers but also provides access to Java NumberFormat API which provides ultimate formatting capabilities. Read more about it [here](https://docs.atlassian.com/software/jira/docs/api/7.6.1/com/atlassian/jira/util/velocity/NumberTool.html).

### Formatting with built-in styles <a href="#howtoformatnumbervalues-formattingwithbuilt-instyles" id="howtoformatnumbervalues-formattingwithbuilt-instyles"></a>

The following is an example of formatting the value of a number field called `"My Number Field"` in various styles.

```
#set ($numberValue = $!issue.getCustomFieldValue("My Number field"))

Integer: $!number.format("integer",$!numberValue)

Number: $!number.format("number",$!numberValue)

Currency: $!number.format("currency",$!numberValue)

Percent: $!number.format("percent",$!numberValue)

Default: $!number.format("default",$!numberValue)
```

### Format with Java Number format <a href="#howtoformatnumbervalues-formatwithjavanumberformat" id="howtoformatnumbervalues-formatwithjavanumberformat"></a>

The following is an example of using Java's NumberFormat to render the number value in Japan's currency:

```
#set ($numberValue = $!issue.getCustomFieldValue("My Number field"))
#set($numberFormat = $!number.getNumberFormat("currency", $!templateSupport.getLocale("jp_JP")))

Currency in Japan: $!numberFormat.format($numberValue)
```
